Dew-Retted Heilongjiang Flax against Imported Water-Retted Bales
Dew-retted Heilongjiang flax provides cost savings for medium counts, while imported water-retted bales deliver the fineness needed for yarn counts above Nm 50.
Elementary Fiber Aspect Ratio
Structural Dimension
Geometric proportion of length to diameter for individual flax cells defines the physical geometry of the primary building blocks within a bundle. Calculating the elementary fiber aspect ratio involves dividing the longitudinal measurement of a single cell by its transverse width. This value remains independent of the total length of the flax stalk.
High ratios generally indicate a more refined biological structure.
Spinning Influence
Processing efficiency during the drafting stage depends heavily on how these individual cells overlap and grip one another. A high elementary fiber aspect ratio provides more surface area for inter-fiber friction when the yarn is formed. This friction prevents premature slippage during the wet-spinning process.
Strength Correlation
Ultimate tensile capability of the finished thread relies on the integrity of these microscopic units. Because the elementary fiber aspect ratio dictates the overlap length between cells, it directly affects the total force required to pull the structure apart. Shorter ratios lead to weaker yarn regardless of the pectin content.
This geometric limit defines the finest possible count a mill can achieve with a given crop. When the ratio is too low, the fibers cannot maintain sufficient contact to withstand the mechanical stress of the weaving loom, leading to high failure rates in the cloth factory.
